V2X infrastructures improve safety on US roads

Connected Vehicle Roadside Units (RSUs) in the US are designed to link public transportation, passenger vehicles, and vehicles on highways, roads and bike paths. The RSUs handle the communication between infrastructure and vehicles; in doing so, they support the prioritisation of buses and emergency vehicles as well as the detection of vulnerable road users.

The backdrop is a US government plan to allocate $6.4 billion over five years to fund projects that reduce greenhouse gas emissions – a budget that will also help support V2X infrastructure projects. In conjunction with these plans, V2X technology provider Autotalks will work with Yunex Traffic to introduce V2X technology in the US. Under the collaboration, the two companies will install Yunex Traffic’s RSU2X, high-performance roadside units (RSUs) for connected vehicles equipped with Autotalks’ V2X chipsets, in the states of Florida and Colorado.

The RSUs allow vehicles and infrastructure to communicate with each other to improve safety and efficiency across all forms of mobility, including public transit, cars, trucks, bicycles and even pedestrians. The announcement came after the US government announced it will provide $6.4 billion over five years for greenhouse gas emission reduction projects, a budget that will also help support V2X infrastructure projects.

Yunex Traffic’s RSU2Xs are deployed on the Colorado Department of Transportation’s road network, as well as in Florida in the city of Tampa, on the Florida Turnpike and on Interstate 4 (I-4). The RSU2X is also an essential element of the Florida Department of Transportation Traffic Engineering Research Laboratory and Tampa Hillsborough Expressway Authority’s pilot projects and tests as part of the nationally recognised Connected Vehicle Pilot (THEA CV Pilot). Some testing and deployment is already underway, but the majority of installations will take place between fall 2022 and spring 2023.

The RSU2X units, which are based on Autotalks’ technology, can be used to connect motorways, roads and cycle paths. They are a key enabler for C-ITS and Connected Roads applications, which are now bringing more adaptive safety traffic management solutions to market and are also expected to enable safer autonomous driving in the future. The RSU2X units are complemented by Yunex Traffic’s new, ready-to-use aftermarket OBU2X on-board unit (OBU), also based on Autotalks chipsets.

The Yunex Traffic RSU2X is the central interface for wireless communication between the roadside infrastructure and the on-board units. The bidirectional communication via the RSU enables both the transmission of information such as speed limits and the reception of on-board messages such as pedestrian warnings, all in real time. The RSU2X provides important data for a more accurate picture of the current traffic situation, enabling more efficient traffic control, a significant reduction in traffic accidents and an even greater reduction in emissions.

“The deployment of our V2X solutions in Florida and Colorado through the partnership with Yunex Traffic is another milestone in our business momentum and takes our entry into the US market to the next level,” said Hagai Zyss, CEO of Autotalks. “The new collaboration comes at a time when the choice of C-V2X over DSRC as the preferred V2X technology in the US has been finalised. The V2X solutions that we and Yunex Traffic offer meet the current specifications and provide security for deployment.”
